Showa
Sonohara Dam spans the Neri River in northern Gunma Prefecture, creating a reservoir that helps regulate a tributary of the Tone River system. Completed in 1965, the dam was developed for flood control and water use, transforming a folded rural valley into a long, irregular water body. Its shores follow the bends of the valley between densely wooded hills in the former Tone area of Numata. This is a quieter face of inland Gunma, shaped by steep terrain and water-management infrastructure rather than the prefecture’s urban centres. The wider Tone basin is vital to water supply and flood protection across the Kantō region, giving this reservoir a practical role far beyond its immediate setting.

Tucked along the northern foothills of Mount Akagi, Showa is a place whose character is shaped by broad upland farmland and the changing conditions of the mountain slope. This village in Gunma Prefecture lies east of the Tone River valley, in an area where fields and small settlements spread across the Akagi Plateau. Agriculture is central to local life, with the cool inland setting supporting vegetable cultivation and konjac production associated with Gunma. Showa was formed in 1958 through the merger of the former villages of Kuroho and Itonose.

Gunma Prefecture is best known within Japan for Kusatsu Onsen, one of the country’s most celebrated hot-spring resorts. Set inland northwest of Tokyo, it spans fertile sections of the Kantō Plain and mountain country along its western and northern edges. The Tone River, Japan’s second-longest river, rises in these mountains and feeds farms, reservoirs and towns. Mount Akagi is a prominent volcanic landmark above the Maebashi area. Gunma also preserves a major chapter of industrial heritage at the Tomioka Silk Mill, Japan’s first modern silk-reeling factory and a UNESCO World Heritage site.

Among the countries of East Asia, Japan stands out for its volcanic archipelago, stretching from the cool north of Hokkaido to subtropical Okinawa. Mount Fuji, the nation’s highest mountain, rises above central Honshu, while the Pacific Ocean and the Seto Inland Sea have long shaped settlement, fishing and travel. Tokyo pairs dense urban life with major museums and neighbourhood traditions; Kyoto preserves temples, gardens and the legacy of Japan’s imperial court. Seasonal customs give journeys a changing rhythm, from spring cherry blossom viewing to autumn leaves. Regional cooking is equally varied, with sushi, ramen and local specialties reflecting coastlines, climate and agriculture.
